Radius of circular path, followed by a c...

Radius of circular path, followed by a charged particle is proportional to ______ .

A

charge of a particle

B

energy of a particle

C

momentum of a particle

D

magnetic field

Text Solution

Verified by Experts

The correct Answer is:
C
Centripetal force = magnetic force,
`(mv^(2))/r=Bqv`
`therefore(mv)/r=Bq`
`thereforer=p/(Bq)" "[becausemv=p]`
`thereforerpropp" "[becauseBq" is same"]`
